TWISTER-ll/IACHINE.

SPECIFICATION formingpart of Letters Patent No. 661,301, dated November6, 1900. Application filed April 13, 1900, Serial No. 12,695. (No modeLlTo @ZZ whom it may concern,.-

Be it known that I, HERBERT Gr. BEEDE, a citizen of the Unit-ed States,residing at Pawtucket, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements inTwister-Machines, of which the followingis a specification.

My invention relates to twisting machinery or what are generally termedtwisters for twisting thread, and more particularly to wet twisters ortwisters in which a trough of water is used through which the threadpasses before it is wound on the bobbing and the object of my inventionis to improve upon the construction of some of the parts of wet twistersas now ordinarily made.

In. the ordinary construction of wet twisters the traverse-rod carryingthe guide-wires through which the threads pass has a reciprocatingmotion in a horizontal plane to change the position of the thread on theglass rod extending in the trough of water and on the top roll, overwhich the thread passes, and prevent the wearing of a groove in the sameby the friction ofthe thread. The guidewires in the traverse-rod throughwhich the threads pass are located at one side of the water-trough anddo not extend over it and are of such a shape that they do not removethe water from the thread and cause it to drop oli?, but allow it to becarried on to the rolls. The position of the guide-wires relatively tothe thread which passes through them is such that though there is areciproeating movement of the wires with the traverserod in a horizontalplane there is no vertical movement of the wires, so that the threadmust always bear at the same point on the wire, and the constantfriction caused by the passage of the thread through the wire will weara groove therein, so that if larger thread or yarn is to be twisted itwill be wedged in the groove and broken off. In my improvements I havemy thread-guide wires extend over the water-trough and make them of sucha shape (with two vertical portions between which and tangential towhich the thread passes) that the wires not only'act as a guide for thethread7 but also remove the water from the thread and cause it to dropoi' from the bottom ot' the wire directly into the trough below. I alsoprovide for a vertical movement of the guide-wires in addition to theordinary reciprocating movement in a horizontal plane, so that thethread passing through the guide-wire does not always bear at the samepoint on the wire, but has a considerable bearing-surface, so that itwill not wear a groove in the Wire by constant friction at one point, asis ordinarily the case, as above stated. In the present instance to givea vertical movement to the guide-wires I provide the traverse-rod, towhich the guide-wires are secured, where it is supported by the standsor brackets in which it has a reciprocating motion in the direction ofits length with a shoe or bearing which has an inclined surface on itslower part to travel on the inclined surface on the traverse-rod stand,so that as the said traverse-rod is given a reciprocating motion in thedirection of its length it will also be raised and lowered according tothe incline of the shoe or bearing thereon and with it the series ofguide-wires.

I have shown in the drawings only such parts of a wet twister with myimprovements applied thereto as will enable those skilled in the art towhich my improvements belong to understand the construction andoperation thereof.

Referring to the drawings, Figure l is an end view of a port-ion of awet twister suliicient to illustrate my improvements applied thereto.The end of the water-trough is removed. Fig. 2 is a section at line 2 2,Fig. l, showing a rear View of the traverse-rod which carries theguide-wires and the mechanism which operates said rod looking in thedirection of arrow a, Fig. l. The watertrough is not shown in thisfigure. Fig. 3 is a cross-section through the traverse-rod on line 3 3,Fig. 2, looking in the direction of arrow c, same i'igure. Fig. :I is aside view oi' the traverse-rod stand and traverse-rod and its inclinedshoe or bearing looking in the direction of arrow b, Fig. 3. Fig. 5 is aside view of a guide-wire detached. Fig. 6 is a sectional view of theend of the glass-rod-supporting finger and clamp shown in Fig. l; andFig. 7 is a cross-section through the clamp, showing the ends of twoglass rods to IOO 2 censor be clamped, taken on line 7 7, Fig. 6,looking in the direction of arrow d. Figs. 3 to 7, in elusive, are on anenlarged scale.

In the accompanying drawings, 1 is a portion of the frame of thetwister. 2 is a stand having at its upper end a bolt 7, which extendsthrough a slot 6 in the slotted segment 6 on the lifter-handle 6, whichis secured by a screw 5 on the lifter-rod 4, which rotates in a bearing3 on the water-trough stand 16. The clamp-handle 8 turns the nut 9 onthe bolt7 to clamp the segment 6 on the lifter-handle 6 and hold thelifter-handle in posit-ion. A finger 10 is secured on the lifterrod 4 bya screw 11 to move with said lifterrod as the same is rotated by thehandle 6. The finger 10 supports at its outer end the ends of the glassrods 12, secured thereto by the clamp-piece 13 and clamp-screw 14, asshown. A projection 10' on the finger 10 rests on the bottom of thewater-trough 15 to support said finger.

It will be understood that there is a series of supporting-fingers 10and a series of glass rods 12, extendingin alinement and supported byand clamped in said fingers 10. The two contiguous ends of two glassrods are sup ported and clamped in one finger, as shown in Fig. 8. Thediameter of the glass rods often varies and the two ends to be clampedin one supporting-finger are rarely of the same diameter. lthereforemake the recessed part on the end of the finger of greater diameter thanthe diameter of the ends -of the glass rods to be clamped and the recessin the clamp-piece 13 of less diameter than the diameter of the ends ofthe glass rods to be clamped, and l make the inner surface of theclamp-piece 13, at its attaching end, slightly convexed or curved, sothat it may have a tilting motion to adjust itself to anyinequality inthe diameter' of the ends of the two glass rods to be clamped. I providetins or ridges 13 on the edges of the clamping-piece 13 to engage andbind the rods near their extreme ends, and not at their extreme ends, tobreak oft the same.

The movement of the lifter-handle 6 from the position shown by fulllines, Fig. 1, to the position shown by broken lines lifts the glass rod12 through the lifterrod 4 and linger 10, and the turning ot' the clamp-handle S clamps the lifter-handle 6 and holds the rod 12 in itselevated position, as shown by broken lines in Fig. 1. Theglass-rodsupporting tingers 10 by means of the extension 10' are allheld in the water-trough 15 in exact alinement to receive the glass rods12 and are then secured to the lifting-rod 4 by the screws 11. Thefingers 10 are then raised by moving the handle 6 into the positionshown by broken lines in Fig. 1 in readiness to receive the glass rods.l2, which are placed end to end (see Fig. 7) in the recessed portion atthe ends of the iingers 10, and then the clamp-pieces 13 put on andsecured in place by the screws 14. This move the water from the thread.

construction provides for a quick and easy assembling of the parts.

The water-trough 15 may be of the ordinary shape and construction andsupported on a series of stands 16, secured to the frame 1. Only onestand 16 is shown in the drawings. To the front ends of the stands 16and at the front edge of the trough 15 are secured the traverserodstands or brackets 17 by a screw 1S or otherwise. Only one stand 17 isshown in the drawings.

On-the. rear of the stand 17 is a projection or lip 17, under whichextends and is held the rod 15', extending along the front edge of thewater-trough. The lip 17 holds the rod 15/ and the edge of the trough 15in a xed position relative to the shank or attaching end of theguidewire 20, so that in the Vreciprocating motion of the traverse-rod19 and the guide-wires 2O thereon there is always a clearance or spacebetween the guide-wires y2O and the edge of the trough 15.

The stand 17 has an inclined base 17 and the parallel vertical walls17'/ and 17'", between which the `traverse-rod 19, carrying a series ofguide- ;wires 20, has a reciprocating movement in the direction of itslength.

Secured to the traverse-rod 19 at the point where it extends through andtravels in the stand 17 is a shoe or bearing 21, which in this `instanceis of angle shape, with one side extending upon the front side of therod 19 and secured thereto by screws 22 and the other side or bottom 21extending upon the lower surface of the rod 19 and made inclined, asshown, to travel on the inclined base 17' of the stand 17, and thuscommunicate an upand-down motion to the rod 19 in addition to theregular reciprocating` motion. An inwardly-extending lip 17""l on thefront wall 17" of the stand 17 extends over the upper edge of the shoeor bearing 21, as shown in Fig. 3, and acts to hold the traverse-rod 19in the stands 17. By moving the rod 19 in the direction of its length,so that the upper edge of the shoe 21 will pass beyond the lip 17, therod 19 may readily be removed from the stands 17.

The guide-wire 20 is screwed into the rear side of the traverse-rod 19and extends over the Water-trough l5, as shown in Fig. l, and ispreferably made in the shape shown with the t-wo vertical portions a d,between which the thread passes in a direction tangent thereto, so thatthe water is removed from the thread and drops off from the bottom loopb of the wire directly into the trough 15, over which the wire extends,as shown in Fig. 1, and the eye c, back of which the thread extends, andthe projecting end cl, under which the thread is passed andwhichservesto hold the thread and prevent it from slipping off the wire,and the shank or screw-threaded attaching end e. The Wire 2O acts notonly as a guide-wire, but also as a drip-wire to re- The thread.

23 passes under the glass rod 12 in the Watertrough l5, through theguide-Wire 20, and over the top roll 21, mounted on a stand 25 in theordinary Way, and over the bottom roll 26 and the guide 27 to thespindles (not shown) in the ordinary Way.

A reciprocating motion is communicated to the traverse-rod 19 by a Worm28, fast on the bottom-roll shaft 29, meshing with a gear 30, fast on ashaft 3l, which has its bearings in the stand 32, bolted to the frame.On the opposite end of the shaft 3l is a pinion 33, which meshes withand drives a gear 34 on a bolt 41 in the stand 32. The gear 34 has aplate 35 and a cam 36 secured thereon by a piu 37. the traverse-rod 19is a slotted piece or .casting 33, having the inclined slot 38 thereinand the friction-rolls 39 and 40 thereon, which travel on the peripheryof the cam 36. The bolt 4l extends through the slot 38', and the head 4lholds the slotted casting 38 on the bolt 41. There is a nut 41 on theotherend of bolt 4l. It will be seen that the rotation of the cam 36,driven by the system of gears, will communicate a reciprocating motionto the traverse-rod 19, carrying the guide-Wires 20, and cause thethread 23, held by the guide- Wires, to move back and forth on the glassrod 12 and on the top roll 24 in the direction of their length, so asnot to Wear a groove therein, and at the same time the inclined shoes orbearings 21 on the rod 19 Will cause said traverse-rod 19 and theguide-Wires 2O to have Aan up-and-down motion, so that the thread 23,passing through the guide-Wires 20, will not bear at the same place onthe guide- Wires, and consequently Will not make a groove in the wires.

The advantages of my improvements will be readily appreciated by thoseskilled in the art.

I provide a combined guide and drip wire which extends over the trough,so that the drip from the thread will drop into the trough, and Iprovide for a vertical movement of the guide-wires attached to thetraverse-rod, as Well as a horizontal movement, and thus prevent thethread from wearing a groove at one point in the guide-Wires.

It will be understood thatl the details of construction of myimprovements may be varied, if desired.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-
